I'm on Buserelin nasal spray 4 times a day. That's me been on it for a week now. Last time I was on it I took it alongside gonal f and the only side effect I had was headaches which I think went away after a couple of days. This time I'm experiencing the following side-effects: really itchy/ irritated nose, increased appetite, and hot flushes (really not enjoyable!). I've a got a cold at the moment too, and and feel really run-down. Honestly cannot wait for the Christmas holidays so I can relax at home and get better before the FET! School is so busy just now. Like you, highhopes, I'm counting the days! Only 8.5 to go!!
